IDEA版本:

查了一部分资料,根本原因如下:

在 Intellij Idea  中使用maven时,所有 scope 为 provided 的依赖都是不会被加入到 classpath 中的,目前该bug尚未被修复。如果你做Spring Boot开发,有带provided的依赖时,直接在IDE中运行项目会导致ClassNotFound异常。

自行查看未修复bug,传送门 —— https://youtrack.jetbrains.com/issue/IDEA-107048

解决方案简单粗暴,找到pom.xml中的如下依赖

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-tomcat</artifactId>
	<!--<scope>provided</scope>-->
</dependency>

将对应的scope 注释掉即可。
